Animated Intersection View for Vehicle Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle navigation systems face challenges in providing clear orientation at complex intersections, leading to driver confusion, missed turns, and increased travel time due to difficulties in visualizing upcoming intersections, especially when roads intersect at different levels or in rotary turns.
Innovation Solution
A vehicle navigation system that includes a location system, navigation database, intersection view database, animation database, and animation player, which processes GPS and motion data to provide animated views of intersections, synchronizing the animation with the vehicle's position and speed to enhance visualization and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the navigation system provides enlarged perspective views of intersections from a standpoint that differs from the actual vehicle position, then the driver can see the intersection layout more clearly, but the driver needs time to become properly oriented which leads to missed turns and increased travel time
Solution Approach 1:
The system performs preliminary action by pre-calculating and storing animated intersection views in the animation database before the vehicle reaches the intersection. The animation player then plays these pre-computed animations in sync with the vehicle's approach, allowing the driver to become oriented to the intersection layout before reaching it, thereby reducing orientation time and preventing missed turns.
Solution Approach 2:
The system applies dynamics by synchronizing the playback of pre-stored animation frames with the vehicle's real-time position and speed. The animation player dynamically adjusts the animation progression based on the vehicle's movement, creating a dynamic visualization that adapts to the vehicle's actual approach to the intersection, making the static pre-computed animations useful for real-time orientation.
2Loss of information
If the navigation system displays complex road geometry in the forward path, then the driver can see detailed intersection information, but the driver becomes confused by the displayed digital map
Solution Approach 1:
The system segments the complex intersection visualization into multiple simplified animation frames that are played sequentially. Each frame represents a simplified perspective of the intersection at a different stage of approach, breaking down the complex geometry into manageable visual steps that are easier for the driver to process and understand.
Solution Approach 2:
The system creates a simplified copy of the actual intersection view through pre-computed animations. These animations are generated from 3D models of the intersection and stored in the animation database, providing an idealized but accurate representation that is easier to interpret than the actual complex real-world view, especially for atypical intersections.
3Loss of information
If the navigation system provides three-dimensional perspective views of intersections, then the driver can visualize the intersection in 3D space, but the complexity of the road geometry causes orientation difficulties
Solution Approach 1:
The system uses dynamic animation playback synchronized with the vehicle's movement to present 3D intersection views. The animation player progressively reveals the 3D intersection model as the vehicle approaches, dynamically adjusting the view angle and detail level based on the vehicle's position, making the complex 3D geometry easier to orient to compared to a static 3D view.
Solution Approach 2:
The system pre-computes and stores multiple 3D animation frames of the intersection in the animation database before the vehicle reaches it. These pre-prepared animations allow the driver to gradually become oriented to the 3D spatial layout as the vehicle approaches, rather than being confronted with a complex static 3D view that requires immediate interpretation.

AI summary
A vehicle navigation system helps guide a driver to a destination by enhancing visualization of upcoming intersections. The navigation system stores animation data that depicts the intersection as it will appear to the driver. The animation data may be a sequence of images (e.g., digital camera images) taken at intervals before and after the intersection. The navigation system may show the images in synchronism with the progress of the vehicle to provide an animated display of the intersection for the driver. The animated display aids the driver with following a recommended navigation route to the destination.
